Who owns and regulates Whitharral WSC?

Does Whitharral WSC have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in April 2026. The violations listed here began between July 2025 and April 2026. By type: 6 contaminant level above the legal limit, 4 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (4 of them). EPA lists 5 as resolved, 4 as archived and 3 as addressed. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
